This invention among other objects aims to provide interlocking Ornamental shingles: which may be produced withoutwaste;

The invention may be readily'understood by reference to an illustrative construction embodying the invention and: illustrated in the accompanyingdrawings." In said drawings: Fi 1 is a plan View of a roof surface formed with interlocked ornamental shingle units; 1 a i a a V Fig. 2 isa plan view, somewhat diagrammatic inrharacter', illustrating the relative arrangement of the shingle unitsin which they may be out without waste from sheet roofing material; i r

Fig. 3 is a perspective view. on an enlarged scale relative to Figs. 1 and 2, of the interlock between a pair of shingleunits; I Fig. 4: is a diagrammaticview showing the interlocking principle applied to a shin-Q gle unit of conventional outline, illustrating how the same may-be cut without-waste from roofing material; i

i Fig. 5 is a View of the same character as Fig. 4 showing the interlock applied? to a square tab shingle unit havingan ornamental outline appropriate to the square tab shingle; Fig. 6 is a similar Viewillustrating the adaptation of another strictly ornamental design to an ornamental"interlocking shingle unit;and

Fig. 7 is a view illustrating the interlock between overlapping units of the character shown in Fig. 4..;. l

The illustrative shingle unit is-designed with a so-called ornamental outline, i. e., an outline other than the conventional or regular outlines presented by square,

triangular or' diamond shapes and'g'enerally including a series of curves arranged and proportioned to present a shingle tab outline which is decorative in character." The design alsoincorporates interlocking means which permits interlocking of shingle'units without mutilating or impairing the general effect of the design.

In Figs.

1, 2 and 3there is illustrated ornamentalshingle unit 10'c0mprisinga pair relates to lock shingles, and

wings 15 and hexagonal, v

of tabs 11 having an ornamental outline' 12 comprising .aseries of ogee curves'connected by short straight lines and proporsv tioned to present a decorative outline; The outline of the end 13 of the tab as well as therecess 14 at the base of theunit between a pair of tabs, embodies laterally projecting a narrower terminal portion.

By making the tabs symmetrical and by arrangmg'th-e des gn so the ornamental shingle may be cut from roofthat one half 17 therev of is m'erely a reversal of the other half18,

ing material without waste; This is illustratedin Fig. 2 wherein the'material cut out to providethe space .betweenone pair; of tabs 7 11, forms the tab 19 of a complementary shingle unit 20'. 'The back edges 21 and '22 ofthe units beingstraightand lying in alignment inthe sheet of roofing material,' a plurality ofscomplementary unltsillustrated in I Fig. 2 may-be cut from a widesheet of material whose width is a. whole multiple of the width A of the strip from which the complementary series of shingleainits are cut. 7 As here shown the ends 23 of the units lie 'atthe. bases of the tabs. Y

In forming a roof covering from the aforesaid shinglesthe latter are laid in overlapping staggered courses 24, 25, 26, etc, with the tip of'thetabs in one course "registering with the bases-between the tabs of the next underlying course, Each course of shingle units is laid with the side edges'or ends 23 outline 31 of the overlyingtab forms'a 'continuation of the adjacent outlines 32 and 33 ofsu ch tab. Thus as shown in Fig. l,the shingle units may be interlocked' at the free ends of the tab in such a way as" to harmonize with the general design and without'dis the narrow space 16 and thereby forming a' I turbing or detracting from. the pleasing or decorative characterof the shingle outline.

, N o cuts or slits for interlocking purposes are necessary, no need any portion of the shingle be folded under to aid infastening down the tabs.

which may be blown up with the possibility of leakage. The depth of each shingle unit is 'suflicient to underlap the tabs of the second overlying course by a safe distance B. Thisafl'ords ample protection in the region of the points between adjacent units in a course. v r

In Fig. 4 there isillustrated a shingle unit comprising a pair of spaced tabs having a conventional outline to which the interlocking principle has be noted that the design of the interlocking and associated elements is such that the end 37 of the tab.iscomplementary in outline to the space 38 between adjacent shingle tabs. Thus the shingles may be out without waste from a sheet of roofing material in'the manner described in connectionwith the shingle unit illustrated in 1 to 3. Theend of each tab- 37 embodies laterally projecting wings 39 and a-n'arrower terminal portion 40 which provides, the narrower recess 41 at thelbase of adjacent tabs under the sides of which the of the overlying shingles, lie to provide an interlock between'theshingle units. The interlocked arrangementbetween overlapping shingles i s illustrated by the shaded outline42 which represents-an overlying, shingle interlocked with the' underlvmg shingle... It will be noted. that the cohtour, 43, at the tip of each shingle tab not only forms a continuation of the outline l l of the adjacent shingle tabs but harmonizes with the general character. of such outline.

In Fig. 5 is illustrated a different form of shingle'unit 45 having a pair of spaced tabs 46' whose-outline is generally rectangular in character. The outlineof the tabs is v exactly complementary to the space 47 between adja- .Cent tabs as is the case with the previously described designs, and embodies the laterally projecting wings 48 and the narrowertermt nal portion 49. In interlocking overlying coursesof shingles the wings 48 of the tabs of an overlying course underlie the portions tween adjacent shingles.

It will having a-pair of shingle tabs embodylng a fleur-de-lis design at the ends 66 of the. tabs andatthe base 67 of and between adjacent tabs. i It will be noted that thespace' is complementary to the outline of the tab and the shingles may therefore be made without waste from a sheet of roofing material. Thefleur-de-lis design embodies the laterallyexte'nding wings. 68 and a narrower'terminal portion 69. When interlocked as illustrated at; the'right hand of thefigure the wings 68 of an overlying shingle tab underlie the portions the base of the space between adjacent tabs. The narrower terminal portion 69 in this case lies in the narrow space 71 provided by the fleur-dedis outline, thus exposing a substantial portion of the fleur-de-lis. design at as adjacent the base 67 The interlocked outline generally carries out the spirit and character-of the main design and does not present any onharmonious elements; 1 V

In laying each of the shingle units illustrated in Figs. 4 to 6, it will be understood that the units are nailed adjacent the bases of the spaces between adjacent tabs before 'the tabs ofthe next overlying course are interlocked, all in a manner similar tothat ends-of the shingle tabs. The latter method I V of fastening shinglesv is difficult and time consuming since a portion of the shingle must be folded and the overlying course can finally be positioned.

It should be noted that the matter of avoidance of waste in the manufacture of shingles and shingle units is important, not so much from the standpoint of saving material but of avoiding'small bits of material accidental- 1y falling units and the units. gles of this 7 a water-proofed so-called felt sheet coated witha heavy asphalt compound which is sur-, faced with a mineral. coating such as crushed slate. The black asphalt compound from any bits of waste material lodging between the permanently staining .thefaces of It will be understood that shinplaced and thennailed before ch ara cter are generally made from T shingle unit's does not reupon the faces of packaged shingle 1 courses of shingle units,

shingles in the packageobviously would permanently mar theface of the material; For this reason, more than any other, the production of waste is highly objectionable, 7

Obviously the invention is'not limited to the details of the specific shingleunits herein i lustrated since these maybe variously modified. j, Moreover it is not indispensible that all features of the invention be used conjointly since various features may advantageously be used in different combinations and sub-combinations.
